An acoustic engineer is investigating the impact of noise pollution on a residential community near a newly constructed high-speed rail line. The engineer uses automated outdoor sensors to record the peak sound pressure level (measured in decibels, dB) of every passing train over a 7-day period, generating quantitative data.
Explain one disadvantage of obtaining quantitative data in this study.
Practise AQA A Level Psychology Research methods with exam-style questions for A Level Psychology. 100 questions covering Experimental method, Observational techniques, Self-report techniques, Correlations, Content analysis (A-level only), Case studies (A-level only), Scientific processes, Data handling and analysis, and Inferential testing (A-level only), matched to the AQA A Level Psychology (7182) specification and written in Paper 1, Paper 2 and Paper 3 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
